Gravitational bending of light rays in plasma

Abstract

We investigate the gravitational lensing effect in presence of plasma. We observe that in a homogeneous plasma the gravitational deflection angle differs from that in vacuum, and it depends on the frequency of the photon. We discuss observational consequences of this dependence for the point‐mass lensing and estimate possibility of the observation of this effect by the planned project Radioastron.
